For an excellent teaching and research resource on the Great Lakes region, check out History of the Great Lakes States website.
As the site’s creators put it, the site “is an online library for the history of the region once called the ‘Northwest Territory,’ that in the early 1800s became the states of Ohio, Indiana, Illinois, Michigan, and Wisconsin.”
The site houses various primary sources such as memoirs, travel journals, magazine articles, novels, biographies, maps, etc. Its extensive list of historical subtopics includes religion, politics and government, culture, society, and economics.
